This is a very strange bug. The SVG icons for the buttons are all being rendered white, and thus invisible against the white background. But when I inspect the element with Chromeās DevTools, I can see no reason for this; their color is not set to white, and I canāt set any CSS overrides to make it anything but white. Iām totally stumped.
I just updated Discourse here, and moved it from the default ābetaā track to the āstable releasesā track so that updates will not have to happen as frequently. But it had no effect on this issue.
Also strange: I administer another Discourse forum thatās running the same version, and this bug is not present.
Perhaps itās a plugin issue. Iāll look into that nextā¦
